The 6CG7/6FQ7 is still in production, the Electro-Harmonix tube (quite good!) is available in standard or gold pins.

The 12AU7 Tung-Sol and B749/12AU7 Genalex reissues are really good too.I use and recommend both highly.

The KT-77 Genalex reissue is off the charts, a superb tube. I cannot recommend it more highly. The 6CA7 EH is another terrific tube, and the Tung-Sol EL34B is quite good as well. The other current EL34s are good tubes too, but those 3 stand out IMHO.

The current generation Tung-Sol 6SN7GTB tube is quite good as well. Is it as good as NOS? In some cases yes, but probably not the very best of the NOS. Of course, the price is not like NOS either. The only beef I have is a number of them have slightly tilted glass bottles, which is cosmetic only but still I wish they were straight!

In your case the replacement of the Sovtek 12AX7s would be my #1 move, followed by a set of KT-77 Genalex. You may like the Sovtek 6SN7s with a warmer toned 12AX7 in place - if not at least try the current Tung-Sols.Your RFT is a FINE tube, leave it.

My $0.02 antway...
